I am redoing a rebuild on a Holley 2300 which is/was on a 304 original to a 1973 1010 Travelall. This second rebuild is due to something not quite right on acceleration, also a “stumble” steady state at 50-60 mph. The first rebuild kit came with a 2 stage power valve. What I removed during the first rebuild was a single stage. No markings on either of those. The power valve in this kit is a single stage marked 10.5. 1. I was surprised the rebuild kit does not include replacement jets. Maybe this is normal. The jets in there are marked 51. Are replacement jets something I have to get on my own? Are 51 “correct”? Should I give something different a try? I live in Fort Worth TX. About 600ft elevation. Should be mostly local driving. 2. On the accel cam. I thought I read on here once to get a accel cam kit and try the blue cam on the #2 hole. Is that correct? Thanks in advance for the help!
